IMPLEMENT FOR INSTALLING AND REPAIRING ELECTRIC CONDUCTORS.

Application filed May 13,

T0 aZ/. whom it may concern Be it known that I, JEREMIAH CRONIN, acitizen of the United States, residing at I'Vapakoneta, in the county ofAuglaize and State of Ohio, have invented certain new and usefulImprovements in Implements for Installing and Repairing ElectricConductors, of which the following is a specification.

This invention relates to an implement for installing and repairingline-wires of high voltage.

The primary object of the invent on is to provide a tool adapted for usein installing and repairing wires of high potential, while the currentor power is on such wires, thus making it possible to make installationsand repairs without interfering with trafiic. repairs on such lines areusually made at night, or at a time when the current is cut off. Theimplement about to be described, is one of a number which I employ formaking repairs on high voltage lines, and it 18 designed for the purposeof raismg the phase wires above the workmen to a safe distance, givingthe workmen an opportunity to seat the cross-arms, insulators and otherattachments for the poles, which later receive the wires and hold thempermanently.

The implement embodies a construction which adapts it to be adjustedlaterally to temporarily receive and raise phase wires of varyingdistances apart, all of which wlll be more fully described in thefollowing speclfication.

Other objects and advantages of the device, than those stated, willbecome apparent in the course of the following description.

In the drawings-Figure 1 is a side elevation of the implement, showingthe insulator-carrying-arms in normal position; Fig. 2 is an edgeelevation of the implement; Fig. 3 is a detail broken perspectiveshowing one of the bands and pulleys for eflecting the lateraladjust-ment of the insulator carrying arms; and Fig. l is an elevationshowing the insulator carrying arms extended or in one of their lateraladjust ments, there being also shown in dotted lines, one of thecross-arms of pole, which aids in supporting the upper member of theimplement, when it has been brought to its uppermost position.

Specification of Letters Patent.

Heretofore, so far as I am aware,

Patented Jan. i, 1913. 1912. Serial No. 697,101.

Referring to the drawings, the numeral 1 designates the fixed rod. Thatis to say a rod which in using the implement, or what we term the strongman is always used from a fixedpoint or station.

The numeral 2 designates the upper movable rod and both rods arepreferably rectangular in cross section, so as to be more readily guidedand prevented from turning. The rod 1 is provided with a guide 4: whichis permanently fixed to the rod, and rod 2 carries a similar guide 8permanently fixed to said rod 2, thus rendering rod 2 capable of slidingadjustment on rod 1, enabling the upper member of the implement to beraised or lowered by a means which will be described presently. The rod2 carries at its upper end a cross arm 5 to which is attached at eachend a guide 6.

The numeral 7 designates two laterally extending arms which arelaterally adjustable with relation to the arm 5. These arms carry attheir inner ends guides 8 and 8 and mounted on the arm 7 are petticoatinsulators 9 having the usual transverse recesses 10 in their upper endsto receive the phase wires. Secured to the insulators by twistingtogether or otherwise, are upwardly extending yokes 11 which serve tocenter the phase wires and keep them always in engagement with theinsulators in all of the points of vertical adjustment.

The numeral 12 designates a rectangular support formed of two sidepieces 13 and a base or cross piece 1 1. Side pieces are pivotedsecurely to two depending brackets 15, firmly secured to the undersideof cross arm 5 at or near its outer ends. The cross arm 14 is providedwith laterally extending ears 16, presenting a bifurcation between whichears or bifurcated ends the arms 13 are pivoted, thus rendering thecross piece capable of a swinging movement. Preferably the arm 14 isprovided with an aperture 1'? and another aperture 18 is provided in therod 2 for the passage of a pin 19 by which the rectangular support 12may be firmly held when desired. The means for raising the upper memberof the implement and the means for extending and retracting theinsulator-carrying arms, consists of a system of pulleys and cords whichwill now be described.

Secured to guide 3 is a pulley 20 and secured to guide 4 is a pulley 21,said pulleys 20 and 21 may be attached to hooks or ring bolts secured tothe guides 3 and 1-. A cord has one end attached to the pulley 21 andthe cord passes over the pulley 20 and then passes over the pulley 21and downwardly in position to be grasped by the workmen or operator, andwhich cord may be attached to a cleat or other device on fixed rod 1when the proper adjustment of the implement members has been accomplished. By this cord it will be readily seen that the upper member ofthe implement may be adjusted with regard to the lower rod, the upperrod 2 sliding through the guide 4 and being guided on the rod 1 by theguide 3. his is for the adjustment of the upper and lower parts of theimplementwith relation to each other. The pulleys 20 and 21 may beeither single sheaved or double sheaved. Now where it is required anddesired to laterally adjust the arms 7 with relation to the cross arm 5carried by the member 2, the cords 23, 2 1 and 25 are manipulated as theexigencies of the case may require. To the guide is attached a pulley26, and attached to the guide 8 is a double sheaved pulley 27, andsecured to the pulley 27 is the cord 23, which passes over the pulley26, and then over the pulley 27 and downward to a convenient point to begrasped by the operator.

Attached to the guide 8 is a double sheaved pulley 28, and attached tothe guide 6 is a pulley 30 and to pulley 28 is attached the cord 24:,which passes over the pulley 30, and over one of: the sheaves of thepulley 28 and down below the implement.

Attached to one of the sliding arms 7 is an eye 29, and the upper end ofcord 25 may be attached to said eye 29, or to the double sheaved pulley27, and this cord passes over one of the sheaves in pulley 28, and thenover one of the sheaves in pulley 27, down to a convenient place for theworkmen. All of the cords after the proper adjustment has been obtained,may be securely fastened to a cleat or other device in order to maintainthe desired adjustment.

In operation, as has already been suggested, the rod 1 is firmly securedto a pole, either a new pole that is to be repaired in the way 01providing it with new insulators, or other necessary devices and whereit will become necessary and advisable to raise the phase wires out ofthe way of the workmen while they are engaged in placing new cross armsupon a new pole or making other desired repairs. The cord 22 ismanipulated to raise the upper member of the implement and when it israised to the desired extent, the cord may be fastened, or the crosspiece 14- ot the support 12 may be raised upon one of the cross arms ofthe line pole 31 shown in dotted lines, Fig. 4, which obviously willhold the upper part of the implement in properly raised position. Bymanipulating cords 23 and 24;, the adjustable arm 7 may be moved to thelimit of their lateral adjustment as shown in Fig. 4e, and the cord maybe manipulated to draw the arms together or to the position shown inFig. 1. The upper member of the implei'nent after the phase wires havebeen united by suitable devices is raised until the insulators engagethe various phase wires between the yokes 10, when the upper part of theimplement further raised to support the wires at a very considerabledistance above the point where they will ultimately rest when the job iscompleted. When the work is completed and the insulators upon thepermanent road pole are in position to receive the phase wires, theupper part of the device is lowered bringing the wires to their properpositions upon a permanent pole insulator, when the implement may bedispensed with, the job being completed when the wires are properlyfastened to their respective permanent insulators.

From the foregoing it will be seen that the implement described may beconveniently employed to raise high potential wires or phase wires veryconsiderably beyond the point where the workmen in fixing the polebelow, will be entirely out oi danger, and it will be understood thatmany modifications involving mechanical skill may be employed withoutdeparting from the spirit of the invention.

1 may dispense with the lateral arm 7, providing a device for use inconnection with a line where the phase wires are 01 uniform distanceapart, in which event lateral adjustment of the insulator devices wouldnot be required. This would dispense with the cords 23, 24 and 25 andthe insulators, and insulator pins would be attached directly to thecross arm 5.

Having thus described my invention, what I claim is:

1. An implement for manipulating line wires, comprising a rectangularframe mounted on a slidable rod or pole, laterallyadjustable armscarried by said frame, insulating devices carried by said arms, andmeans for raising and lowering the slidable rod or pole and thereby theframe and insulating devices.
